Consulting the mann whitney table at 005 level t

Consulting the Mann-Whitney table at 0.05 level, Twould need to be less than or equal to 88 to reject. Itis not, so we conclude that there is no evidence thatgenetic diversity affects abundance (p > .05).(b) (4 points) Since the deviations from respective medi-ans are exactly the same in both groups, the p-valuewould be exactly 1.Thus,p >0.20 is the correctchoice.(c) (2 points) True. We only get as many df as numberof pairs.(d) (2 points) True. If there is more variability betweensample units than there is within a sample unit, pair-ing is usually a good idea.(e) (4 points) Power =αwhen the true difference equalsthe difference under the null, which is zero in thisexample.Thus, the solid curve is not correct be-cause the power is less than 0.05 at zero. Of the twoother curves, the one that slopes up more steeply(dot-dashed) has the higher sample size of 30. It hasa value of 0.85 at a difference of 1, and thus the an-swer isn= 30.3 (22 points)dfTrt= 3-1 = 2,dfErr= 8 + 6 + 4-3 =15, anddfTot= 2 + 15 = 17.The grand mean is

What students are saying

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

Temple University Fox School of Business ‘17, Course Hero Intern

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
